ELECTRICITY POWER METER CIRCUIT

The SC7751 is a high accuracy fault-tolerant electrical
Energy Measurement IC that CAN provides superior stability
and accuracy over extremes in environmental conditions and
over time. The SC7751 does not exhibit any creep when there
is no load.
The SC7751 supplies average real power information on the
low frequency outputs F1 and F2. This Logic outputs may be
used to directly drive an electromecanical Counter or Interface
to an MCU. The CF Logic output gives instantaneous real
power information. This output is intended to be used for
calibration purposes, or interfacing to an MCU. The SC7751
incorporates the fault detection scheme that warns when the
two input currents differ by more than 12.5%. Billing is
continued using the larger of the two currents. By Silan
